CLEARER FOR DRAWING FRAMES.

Application filed August 15, 1924. Serial No. 732,186.

To all whom it may concern:

Be it known that I, PERCY A. I-Ioon, of Yarmouth, Nova Scotia, a subject of George V, King of England, have invented a new and useful Improvement in Clearers for Drawing Frames of which the following is a specification.

My invention relates to clearers for draw ing, slubbing, roving frames and the like, and its novelty lies in an attachment to the cover of the drawing frame such that the waste will be wiped off from the front roll before it has a chance to be woundunon it.

My invention will be understood by ref erence to the drawing which shows t drawing rolls, the cover and the attach inent all in vertical section, the other parts of the frame being omitted. as being unnecessary to the understanding of my invention.

1,8, 3 and l indicate pairs of drawin rolls suitably mounted, each pair comprising an upper roll and a lower roll between which passes the sliver A in the direction indicated by the arrow. Movement is given to these rolls in any desirable way. 5 is :1 cover of usual character and mounting, having a boss 6 to which is attached a clearer board 7 under which is a clearer pad 8 usually of felt. cloth or the like. These parts may be of usual construction.

To the front inner wall of the cover is attached by screws 9 an angular strip 1.0 of stiff material such as fibre board, its horizontal portion or free end 11 projecting forward from the cover sufficiently far ti reach to about the centreof top roll 1. This wiper, as I call it. extends the length of the cover so that the end of its horizontal. portion will be in close nroxiinity to the entire length of the ton roll and may even engage it. Its proximity to the top roll should be sufiicient to enable it to nrevent any waste to be carried past it by the top roll. Thus the waste cannot wind'u'pon the top roll and prevent its effective action.

I prefer that the free edge of the wiper shall reach far enough forward to engage the clearer pad. or rather that the clearer pad shall engage the edge of the wiper to secure good work by co-operation with the wiper, if any minute fibres shall be carried by the roll beyond the wiper as is possible owing to the fineness of the fiber.

It will be seen that any waste tending t wind U1) on the front top roll 1 will strike the under side of the part 11 of the wiper.

and sing through will be seized by the clearer pad and prevented from dragging back, which it has a tendency to do, by the winer.

The winer is preferably made of fibreboard which is economical and has sufficient stiffness for the purpose and in practice has n'roved very satisfactory, and yet is sufficientlv soft not to cause wear fron'i-contact with the surface of the roll should it rest upon it. It may be made of other material, however. When the front top roll is metallic it is best that the wiper should not be n actual contact with it.

l 'v hat I claim as my invention is 1. In combination with the front top roll a drawing frame or the like a cover and a wine-r mounted thereon having a substantia lv horizontal portion the free edge of I .h reaches to about the centre of front top roll and in close proximity thereto.

In a drawing frame comprising top" rolls and having a covena wiper attached near one edge thereof to said cover and having a horizontal portion. the extreme edge of such horizontal portionlying in close ;i.roxiinity to the front top roll to wipe waste therefrom.

In drawing frame. a drawing? mechanis con'inrising a top roll. a cover for said i ,e. a. ism, an angular wiper one is attached to said cover, the r ed e of which rests on said top roll. l a clearer pad mounted in engagement with said drawing mechanism and having one edge in substantial contact with said wiper whereby it may cooperate with said winer to preventfibres from winding on said top roll.
